I suspect if they were to cause great harm, we would have known by now. Known how, exactly. The only way that would be known is via official statistics, but the only sources of such data have serious reliability problems. Additionally any paper that tries to use these stats to do any analysis struggles to get published or gets immediately retracted because some people don't like the conclusions. One thing that's undeniable though is that earlier vaccines had their approvals pulled after fewer reported deaths than these vaccines have racked up from just single causes of death alone. The same safety standards as before are not being applied. Thus it cannot be said that these vaccines are "safe", compared to earlier vaccines.
